Apparatus for reducing noise in high-frequency band. |
摘要 |
<p>An apparatus for reducing noise in the high-frequency band is provided in the preceding stage of a limiter (8) with a high-frequency band correcting filter (12) for reducing a high-frequency band component of a reproduced RF signal from an optical disc. The reproduced RF signal has its high-frequency component lowered before entered into the limiter (18), reducing noise and beat components. As a result, a signal which is less influenced by the noise and beat and has good S/N can be obtained.</p> |
